Regarding the heat insulating box disposed as a heating element to prevent burning, its purpose is to bend and extend a part of the refrigerant piping disposed around the opening to heat the front part of the partition member. By using a heating element, the number of welded parts of the refrigerant piping is reduced, and the part where the refrigerant piping that heats the front part of the partition member extends from the refrigerant piping arranged at the peripheral edge is an opening in the inner box. By creating a structure in which the foamed heat insulating material is extended from the communication portion formed on the peripheral edge, it is possible to easily achieve a structure in which the foam heat insulating material filled between the inner box and the outer box does not leak from the extending portion, and also In a structure in which a partition member is inserted into an inner box to divide the inside of the refrigerator into upper and lower chambers, the inner box is prevented from being deformed by the foaming pressure of the heat insulating material filled between the inner box and the outer box. To provide a structure in which the partition member can be accurately inserted and supported into the inner box with sufficient pressure by an inner jig inserted into the inner box.

われる。 In order to achieve the above objects, embodiments of the present invention will be described below in detail with reference to the drawings. Reference numeral 1 indicates a two-temperature refrigerator body, which includes a heat insulating box body 2, a freezer compartment door that closes a freezer compartment opening 7A (not shown), and a refrigerator compartment opening 8A.
It consists of a refrigerator door that closes off the refrigerator compartment. The insulating box body 3 is composed of an outer box 3, an inner box 4, and a heat insulating material 5 such as foamed polyurethane filled between the two boxes, and is divided into a freezer compartment 7 on the upper side and a refrigerator compartment on the lower side with a partition member 6 inside the refrigerator 2A. Section 8 is formed. A cooler, which is a part of a refrigeration cycle (not shown), is disposed inside the partition member 6, and the cooled air inside the refrigerator is forced into the freezer compartment 7 and the refrigerator compartment 8 by an electric blower (also not shown), and is cooled to a predetermined level. maintained at temperature. A refrigerant pipe 9 made of a flexible material such as copper or aluminum is disposed around the opening of the heat insulator box 2 and on the front surface of the partition member 6. Inlet pipe 10 and outlet pipe 1 of refrigerant pipe 9
1 enters the outer box 3 through the holes 14 and 14' in the bottom plate 3C of the outer box 3, extends forward along the bottom plate 3C, and connects the outer flange 17 and the inner flange 15 through the cutout hole 16 of the inner flange 15. It enters the U-shaped groove 18 formed by. The refrigerant pipe 9 is bent into a substantially square shape along the opening of the outer box 3, and is bent into a U-shaped groove 18.
It is arranged so as to come into contact with the back side of the outer flange 17 inside and to go around the outer casing opening periphery. Refrigerant pipe 9 as shown
The middle part of the right side, that is, the part facing the partition member 6 is bent into a U-shape (hereinafter, this part 13 will be referred to as the partition pipe). Partition pipe 13 of refrigerant pipe 9
As shown in FIG. 5, it is initially bent so as to stand vertically to the opening of the outer box 3. U-shaped groove 1
The inner box 4 is housed in the outer box 3 with the refrigerant pipe 9 disposed inside the inner box 8. The inner box 4 is one inner box that extends from the freezer compartment to the refrigerator compartment, and is made of a material such as plastic by a vacuum forming method, etc., and has a U-shaped groove on the periphery of the opening of the outer box 3. 18
A collar 19 is provided outwardly for engagement within. After pressing and inserting the short elastic sealing material 21 into the U-shaped groove 18 that accommodates the refrigerant pipe 9, the inner box 4 is opened while applying an appropriate force using its own deformability. It is inserted through the front opening 3A of the outer box 3 while being retracted, and the collar 19 is inserted into the U-shaped groove 18. Note that the collar 19 of the inner box 4 is an elastic sealing material 21.
At this point, the collar 19 comes into contact with the back side of the outer flange 17 of the outer box 3. However, in the middle part of one side of this collar 19, that is, the part facing the partition member 6, there is a groove on the back side of the outer flange 17 over its entire width. A recess is formed that is spaced apart from the recess so as not to come into contact with the inner box 4, thereby forming a recess that creates a step that is recessed toward the back. There is. When the inner box 4 is stored in the outer box 3, the partition piping 13 is raised vertically, so that it can be easily stored without causing much hindrance. Further, the partition pipe 13 is connected to the outer box 3 formed by the communication part 20 provided in a part of the collar 19.
The space between the outer box 3 and the inner box 4 allows it to extend outside the outer box 3 without any problem. The assembled inner box 4 and outer box 3 are placed on the jig 22 with its opening facing downward. At this time, the inner surface of the inner box 4 comes into contact with the outer surface of the inner jig 22 of the jig 22, and the partition pipe 13 of the refrigerant pipe 9 enters the hole 23 bored in the jig 22. A foamable heat insulating material 5 is injected and foamed by covering the outer periphery of the outer box 3 with an outer jig (not shown), and after curing, the outer jig is removed and the heat insulating box body 2 is removed from the jig 22. The partition member 6 is stored in the completed insulation box 2, and the partition piping 13 is bent in the direction shown by arrow P in FIG. 7 so that it is on the same plane as the opening of the insulation box. The metal fittings are fixed to the partition member 6 with screws.
If the partition part backing plate 6A made of a magnetic material, which is the front surface of the rear partition member 6, is fixed, the partition part piping 1
3 comes into contact with the back surface of the partition part contact plate 6A, and the communication part 20 is covered by the partition member 6 and the partition part contact plate 6A.

1 is connected to a refrigeration cycle that cools the inside of the refrigerator 2A. It is connected between the discharge port of the electric compressor and the capillary tube as a pressure reducer so as to function in the same way as a condenser. The refrigerant flowing in the refrigerant pipe 9 is at high temperature and high pressure (therefore, the refrigerant pipe 9 becomes a part of the high-pressure side refrigerant pipe), and in the process of flowing, it radiates heat and condenses, becoming a liquid refrigerant and facing the capillary tube. Therefore, the opening periphery of the heat insulating box 2 and the partition part backing plate 6A are heated by the heat radiation, and a sufficient effect of preventing dew formation can be obtained.

対するシール構造も著しく簡略化できる。 In addition, since the refrigerant piping is drawn out from the communication part that creates a gap between the outer box and the inner box, it is more difficult to block this hole than when the refrigerant piping is led out from a hole formed in the side wall of the inner box. Separate parts such as a lid are not required, and the sealing structure for the heat insulating material filled between the outer box and the inner box can be significantly simplified.
更に、内箱を外箱に組み込む際にも上記のよう
